FAQ

1. What does the part number “DLLA144P184” mean and is it a direct replacement for my current nozzle?
The “DLLA” designation indicates a Bosch-style throttle pintle nozzle. “144P184” specifies the exact hydraulic flow rate and spray angle. This nozzle is a direct replacement for any injector originally using the Bosch part number 0433171161 or labeled DLLA144P184. Always check the number stamped on your existing nozzle to confirm compatibility.

2. What is the recommended installation procedure for this nozzle?
Installation should be performed by a qualified diesel technician. The nozzle seat and sealing washer must be clean. Critical: The nozzle must be torqued to the manufacturer’s specification to avoid distortion. Do not interchange nozzle holders without proper calibration, as this can affect the opening pressure.

3. How can I ensure the longevity of this injector nozzle?
Longevity is heavily dependent on fuel quality. Always use clean, high-quality diesel with proper lubrication properties. Regularly replace fuel filters and drain water separators. Contaminants are the primary cause of nozzle failure. Following the engine manufacturer’s maintenance schedule for injector servicing is recommended.
